ASRock FM2A85X Extreme6

"Unlike some other boards, this ASRock FM2A85X Extreme6 uses slightly thinner IO designs in order to fit in a ClearCMOS button. The downside of this is that for the USB 3.0 slots on the left, any large and bulky USB devices may not fit properly if a DVI-D cable is being used at the same time. We have seen this before on other ASRock models."
